Sauroctonus

Extinct genus of therapsids

Sauroctonus is an extinct genus of gorgonopsian therapsids who lived during the end of the Middle Permian in what is now European Russia. The first fossils, discovered in Tatarstan, were initially believed to belong to a new species of the South African genus Arctognathus. The taxon was designated as such until 1940, when it was assigned to the genus Inostrancevia by Ivan Yefremov, before being definitively classified in a separate genus erected by Alexey Bystrow. The most complete, known fossils of S. progressus include cranial and postcranial elements, currently all recorded from Tatarstan. These elements show that the animal was a mid-sized gorgonopsian.
